Blagojevich is known for a phone call, recorded by
the FBI, allegedly conspiring to sell President Barack Obama's vacated U.S. Senate seat. The
GOP robocall incorporates a portion of the infamous conversation from the FBI tapes.

“I bet you J.B. can raise me money like that,” Blagojevich said
in the recording. “If I can get J.B. to do something like that, is it worth
giving him the Senate seat? Incidentally, he asked me for it. Don’t repeat
that."

Pritzker was subpoenaed by the grand jury of the U.S.
District Court in 2008 during the investigation into
Blagojevich's activities, and he was ordered to provide all documents, records and electronic
media regarding Blagojevich and his cohorts to the grand jury. The billionaire had raised money for Blagojevich's political campaigns.

“For years, J.B. Pritzker has worked behind the scenes to
screw Illinois taxpayers," Illinois Republican Party Spokesman Steven
Yaffe said. "Pritzker provided nearly a million dollars to Mike Madigan’s
political front group and inserted himself into Rod Blagojevich’s criminal
scheme to sell Illinois’ U.S. Senate seat. J.B. Pritzker is just another corrupt
political insider.”
